  The Coinbase FOMO Calculator2022 · vidacode.github.io · ▲108

  Made this using Power BI and the Crypto Watch API. Started making this in November 2021, but never got around to publishing it, so that is the reason for the 'FOMO' in the title - probably a good thing if you 'missed out' on the crypto hype late last year. Now it serves as a way to see how much you 'saved' by not putting in money. Hope someone finds it fun!

  I built a tool to manage and compare credit card rewards2025 · rewards.getonecard.io · ▲87

  This is a free tool that helps you manage and visualize your credit card rewards across different categories. You can input the cards in your wallet and see how they complement each other, spot gaps in your setup, and also see the best card to use for a given merchant. I’m also a founder at OneCard, where we’re building a smart card that’ll eventually handle all of this automatically, routing each purchase to the best card in real-time. Would love feedback from the HN community!

  I built a hardware processor that runs Python▲983

  Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
